1.The structure and working principle Composed of electric oil pump, high-pressure oil tube, fast connection, the working oil cylinder, a piston, pipe bending parts [including plate, on the lower plate, head, the roller]. High pressure oil output by a electric oil pump, high pressure oil pipe into working cylinder, high pressure oil push the work within the cylinder piston, generate thrust, bending tube by bending parts 2. Purpose Pipe bending machine is suitable for factories, warehouses, ***ks, construction, railway, automobile, etc according to the pipeline and repair. Not only have the functions of elbow pipe, it can unload the bend parts (cylinder) as a separate hydraulic jacking machine use.
